As shown in the "SYNOPSIS" you must set the CPANPLUS configuration variable no_update to a true value to use this source engine. This prevents CPANPLUS from attempting to update CPAN indexes.

Attempting to searches and getting a list of out of date modules in CPANPLUS are incredibly slow due the million or so web accesses that are incurred.

I have included two scripts in the examples directory of this distribution that may be of use. installer.pl does installation of modules and updater.pl will find out of date modules and prompt to update them.
